Claims. (Cl. 266-23) in a torch cutting machine a pivotally mounted motor for actuating a torch arm.4`

Another object of this invention is to provide a motor driven torch actuating member.

Other features and advantages will become more readily apparent from the following descripr .Y

tion and the accompanying illustrative drawings in which:

Figure 1 is an elevational view of my machine,

Figure 2 is a top plan View thereof,

- Figure 3 is an end elevational view of the machine shown in position, and

. Figure 4 is a sectional elevation taken on line 4-7-4 ofV Figure 2.

The same reference characters indicate the same parts in the drawings and in the specification and in which I0, indicates my structural steel cutting machine rwhich consists of a stand upon members I2 and I3, for supporting the machine, and a table |4, for supporting the Work I5, to be cut. The upper ends I6 and l1, of the members I2 and I3, carry tracks I8 and I9, formed of T-irons, on the heads and 2|, of which operate the channel wheels 22 and 23, connected by yokes 24 and 25, which with the K angle calibration table 26, supportedthereby and xed to the upper ends 21 and 28, thereof form a carriage 28. Above said member 29, is pivotally mounted, by means of a pin 30, a turntable 3|, between which members 26 and 3|, are mounted, on said pin a spacer disk 32, and indicator disk 33, a gear wheel 34 and a spacer 35, all of the members 3|, 32, 33, 34 and 35, being keyed to the pin 30. A worm gear 36, operated by a crank handle 31, is meshed with (but now shown) the gear 34, whereby said members 3| to 36, and the elements supported thereby are horizontally rotatable.

The table 3|, is provided with vertically disposed integral arms 38 and 39, the upper terminals 40 and 4|, of which form bearings for a horizontal pivot rod 42, upon the end 43, of which is keyed a segmental gear 44, meshed with a worm gear 45, supported in bearings 46 and 41. This gear 45, is also controlled by a crank arm 48. Fixedly mounted upon the shaft 42, are spaced plates 49 and 50, Which are mortised and bolted at their respective ends to the flanges 5| and 52,

of inverted L-irons 53 and 54, the horizontal flanges 55 and 56, of which form a mounting for the torch controlling mechanism about to be described.

The rear ends 51 and 58, of said membersk 53 and 54, are xed across plate 59, provided with a slot 60, Within which may be seated the base 6|, of an` elongated rack bar 62, upon the rear portion 53 of which is secured a bearing member 64, by pins and 65 upon which are pivotally mounted the rear ends 66 and 61, of elevating arms 68 and 69, the forward ends 10 and 1|, are xed to stub shafts 12 and 13, fixed to sprocket wheels 14 and 15. Trained over these sprockets are chains 16 and 11, operating over sprockets 18 and 19, fixed on a shaft 80,rotatable by a crank handle 8|.

Also xedly mounted on shaft 80, at opposing ends thereof are sprockets 82 and 83, driving chains 84 and 85, in turn trained over sprockets 86 and 8'1, fixed on stub shafts 88 and v89, which have bearings at 90 and 9|, of the elevating arms 92 and 93, the ends 94 and 95, of which are brought together and pivoted -on bolts 96 and 91, carried by a slide 88, through which member 6|, slides, hingedly mounted upon the slide 98, is an electric motor 99, which drives the gear |00, adapted to mesh with rack 62. The hinge mounting permits to disengage the gear wheel from the rack 62 if desired.

On the forward end IOI, of said member 62, is carried a torch |02, by means of an inversion knuckle |03, whereby the torch may be adjusted to any desired angle. The extending ends |04 land |05, of members 92 and 93, are provided with adjustable stops |06, engageable with a member |01, carried on member 52, whereby the elements of bar 62, may be adjusted in secure angular position (see Figure 1), for true vertical position of bar 62, when cutting in vertical plane.

The segmental gear 44, is calibrated as at 44', by means of which calibration taken with the pointer |08, the member 62, may be adjusted to any desired upright angular position.

The operation of the device is as follows:

The entire machine I0 is moved on track 20 and 2| to the desired position of the cut on Work I5, and is locked in position by means of screw clamp |09, actuated by pivoted handle H0'. By means of crank 31 the adjustment to the desired horizontal angle of cut is performed which is indexed on calibration 26. A further adjustment is made by means of crank 48 which serves to obtain the desired vertical angle of cut, which is j indexed on calibration 441, as indicated by |08.

At means of inversion knuckle |03, the torch is adjusted to the desired bevel of cut.

With rack bar 62, in horizontal position a 1 horizontal cut on work l5, is made; then the torch is returned to clear flange after disengaging the motor and pushing it back manually the rack bar 62 is raised by means of crank' 8l to vertical position and the vertical lcut on i'iang of work I is made. To accomplish `the diagonal length or long angular cut the head of the ma `chine is moved on the carriage of machine 50-1-5! on mortised track IIU-I l I-I |2I I3 and is locked in position by screws lI5-l Il'l lle-:l l8.

l IY claim as new and desire to procure by Letters Patent is:

1. A'machine for controlling a cutting torch comprising a carriage, a turntable thereon, a piv.-

oted bar for carrying the torch, means for acuating said bar to raise and lower the same, means l for longitudinal movement of the bar, said last means being a motor hingedly mounted adjacent said bar, said bar being a' rack bar and said motor including a gear adapted to mesh with the rack, a pivotally supported mount for the bar, a

segmental gear for actuating said support and forming an inclinorneter, said carriage having a calibrated surf-ace and Vsaid turntable having a pointer operating over the calibrations.

2. A machine for controlling a cutting torch comprising a carriage, a turntable thereon, a pivoted bar for `carrying the torch, means for actuating said bar to raise and lower the same, means for longitudinal movement `oi the bar, said last 4 means being a motor hingedly mounted adjacent said bar, said bar being a rack bar and said motor including a gear adapted to mesh with the rack, a pivotally supported mount for the bar, and a segmental gear for actuating said support and forming an inclinometer. f

3. A machine for lcontrolling a cutting torch comprising a carriage, a turntable thereon, a pivte'd bar for carrying the torch, means for actuating said bar to raise and lower the same, means for longi-tudinal movement of the bar, said last means being a motor hingedly mounted adjacent said bar, said bar being a rack bar and said motor including a gear adapted to mesh with the rack, and apivotally supported mount for `the bar.
